l This invention relates ,top'telephone pay stations and moreparticularly toxcovers or doors for coin receptacles or boxes therefor.

Telephone pay stations at which coins are deposited by the user inpayment for completed calls are provided with receptacles for thereception of thedeposited coins. In some casesstations of this typearelocatedin public places where there is no attendant.A

The door ofthe coin box is exposed and unscrupulous .persons ,sometimesbreak `into the boxes by prying off the door, vdrillingv into it ,or byother means. lt is, therefore,

A desirable that this door be as strong aspos- 45 sible and so formedwithrespect to the open# ing in which it lits so that it will beimpossible to pry the door loose from the receptacle. i

Anl object of the invention, therefor-aisl to strengthenthe cover ordoor. of coin receptacles so as to prevent' access to the `receptaclesby 'unauthorized persons and at the same time to reduce the cost ofproduc-` tion.

In accordance with thisinvention the door for the coin receptacle ismade of manganese steel and cast into shape to closely flt the openingof the coin receptacle. Since this casting cannot easily be drilled toattach a supporting member to the inner surface thereof, a locksupporting member having flanged ends is embedded, that is, molded intothe casting at one end of the door and a pair of plates equipped withprojecting ends formed into overhanging lugs are embedded, that is,molded into the other end of the casting for supporting the door at thelower edge of the opening in the coin receptacle.

This construction forms a strong closure for v coin boxes for telephone.pay stations so th at unauthorized persons cannot gain entry to thecoinboX by prying the coveroff or drilling through the hard steel door.Furthermore, the molded type of door reduces the cost of manufacturesince the number of operations for assembling the door are reduced.

The invention may be more easily understood by referring to thefollowing detailed description in connection with the accom'- panyingdrawing krim 11.

IFig. is a sectionalside view fof a coin receptacle to show the improveddoor made in accordance with this invention; Fig. -2 is a rear plan viewof the `cast door showing the lock supporting member and lug platesembedded in the door;

Fig is across-sectional view of Fig, 2 on the lines 3--3y to illustratethe flanged ends of the lock supporting `member einlbedded in thecast'door; and 4 G0' Fig. 4 is a cross-sectional view ofthedoor of Fig.20u the lines P-4 showing-the lug .plates embedded in the door. j

Referring to the drawing-infFig. 1 is shown a metallic cash receptacle10 having 6,5 an opening in the lforwardend which is surrounded by anoutwardly curved beveled v A door 12 closely fits into the beveled .rim11 of the receptacle 10 and is formed ofyhighly refractory instal, suchas '110 manganese steel; Sincey this material cany not `,easilybe'machined, it is preferable .to cast-the door into a desirableshapevto fit the opening andas yshown inthe drawing, the cast door isrelatively thick and the "i5 edges are beveled toward the outer surfaceto present a surface of minimumy leverage for a tool which might beinserted between the adjacent edges of the door and the receptacle. j eSQ j In accordance with this invention the lock supporting member 13 isformed o-f strip steel orl other suitable metal bent into a U- shapedstructure having angular portions 15 which are embedded in the cast door12. 8JV

having reinforcing end portions 17 and 18 90 projecting out from therear surface of the door. As shown in Fig. l the L-shaped lugs 16 andthe reinforcing ends 17 and 18 of the plates 14 engage the inner surfaceof the rim '11 on the receptacle 10 and the 95 inner surface of the door12 adjacent the lower end engages the outer surface of the rim 11 onthe' receptacle.

A. unitary structure is thereby provided andthe weaknesses of a doorwith members 00 welded, riveted, avoided.

The cast manganese steel door offers a strong closure for the cashreceptacle of the telephone set and it is very difficult to obtainaccess to the interior by the use of drills or prying implements. Itwill be seen that the losses occasioned by unscrupulous persons breakinginto the coin boXes will be stopped and this destructive practicediscouraged. Furthermore, the improved door offers reduction in the costof manufacture, since the number of operations for assembling the dooris reduced to a minimum.

What is claimed is;

l. A coin receptacle comprising a compartmenthaving an opening therein,a cast steel door for closing said opening,a plurality of lugs of stripsteel, each of said lugs having aflat portion rigidly held between theouter and inner layers of said door and another portion projectingthrough the inner' or screwed thereto are layer for engaging the insideof the comhv partment at the edge of the opening therein.

2. A coin receptacle `comprising a compartment having an openingtherein,a cast steelV cover for closing said opening, a U- shaped strip steelmember having oppositely projecting arms rigidly held between the outerand inner layers ofsaid cover, said U-shaped member lprojecting throughthe inner layer of saidcover, a lock supported on said member and a lugof strip steel having a flat portion rigidly held between the oute'randinner layers of saidcover and another portion projecting through theinner layer, said lock and said projecting portion of the lugbeingadapted to engage the inside of the compartment at the edge of theopening.

3. In a coin receptacle, a casing having an opening therein, a covertherefor comprising a cast steel plate for closing said opening, and asupporting lug of strip steel having a flat U-shaped portion embedded inthe material of said plate and extending parallel to the surfacethereof, said flat portion having upturned outer edges projectingthrough the surface of said plate, the lower edge having a partextending parallel to the surface of said plate for engaging the edge ofsaid opening.

4i. A coin receptacle comprising a coinpartment having an openingtherein, a cast steel door forvclosing said opening and a supportingmember of sheet steel having a flat portion permanently embedded in saiddoor between the inner and outer surfaces thereof and two substantiallyparallel upturned portions projecting through the inner surface of saiddoor, said projecting portions being longitudinally extended beyond theembedded portion and adapted to engage the inner edge of said opening.

A coin receptacle comprising a compartment having an opening therein, acast `steel door for closing said opening and a supporting member 0fsheet steel having a fiat portion permanently embedded in said doorbetween the inner and outer surfaces thereof, and three upturned edgesprojecting through the inner surface of said door and adapted to engagethe inner edge of said opening, two of said edges being substantiallyparallel and the third extending between them.
